| Abstract |
Cadmium sulfide and zinc sulfide (CdS and ZnS) were incorporated in sodium- and cetyltrimethylammonium-montmorillonites by the precipitation of sulfides from soluble metal sources in the presence of montmorillonites. The resulting hybrids were characterized by XRD, TG-DTA, TEM, Raman, UV-Vis and photoluminescence spectroscopies. The absorption onsets due to CdS and ZnS in cetyltrimethylammonium-montmorillonite appeared in a shorter wavelength region (311-520 nm) if compared with that (309-484 nm) of the two semiconductors in sodium-montmorillonite, reflecting the difference in the particle sizes of CdS and ZnS in the hybrids. The appearance of the broad emission bands combined with the bands centered at 469, 451, 440, and 431 nm due to CdS and ZnS were attributed to the existence of both CdS and ZnS in the products. The difference in the emission intensity of the hybrids was discussed in terms of the role of cetyltrimethylammonium cation. The unique optical properties of the two products were thought to occur through the interactions of sulfides with their environment (montmorillonite and cetyltrimethylammonium cation). |
